The dispensing slider is provided with a discharge channel communicating with the feeding groove for screws to fall into the discharge hole. The dispensing slider is provided with a floating device for dispensing screws communicating with the discharge channel. Compared with the prior art, the dispensing slider of this utility model can smoothly deliver screws into the discharge groove, which can avoid screw jamming.

[0004] However, the aforementioned patents have the following shortcomings:

[0005] The aforementioned patent describes a method that uses a material separating slider to smoothly feed screws into the feeding trough, preventing screw jamming. However, it can only separate one screw at a time, resulting in low separation efficiency. Furthermore, it cannot continuously feed screws, leading to low manual feeding efficiency and reduced screw separation efficiency. Summary of the Invention

Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0034] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0035] Please see Figure 1-3 This utility model provides a technical solution: an automatic screw dispensing mechanism, including a dispensing component 1 for dispensing screws. The dispensing component 1 includes a support base 11, with an installation groove 111 inside the support base 11. The upper surface of the support base 11 has a V-shaped sliding groove 112 that connects to the installation groove 111. A sliding plate 13 is slidably connected in the installation groove 111. Two sliding grooves 131 are provided on the sliding plate 13. Dispensing blocks 14 are slidably connected in the two sliding grooves 131. A slot 141 is provided on the side wall of the dispensing blocks 14, and limit posts 142 are fixedly installed on both dispensing blocks 14. Both limit posts 142 are slidably connected to the sliding grooves 112. An electric push rod 12 is fixedly installed on the side wall of the support base 11, and the telescopic end of the electric push rod 12 is fixedly connected to the sliding plate 13.

[0036] In this process, the electric push rod 12 drives the sliding plate 13 to move laterally within the mounting groove 111, while the limiting post 142 slides within the "V"-shaped sliding groove 112. The sliding groove 112 drives the limiting post 142 to move, causing the material distribution block 14 to slide within the sliding groove 131. When the limiting post 142 is at the lowest point of the sliding groove 112, the locking groove 141 engages with the screw. When the limiting post 142 moves to the highest point, the material distribution block 14 slides back into the sliding groove 131, thereby releasing the screw. The sliding plate 13 repeatedly moves horizontally within the mounting groove 111, and the two material distribution blocks 14 perform material distribution, resulting in higher material distribution efficiency.

[0037] The support base 11 has two discharge holes 15, and two guide pipes 151 are fixedly installed at the bottom of the support base 11. The two guide pipes 151 are connected to the corresponding discharge holes 15.

[0038] When the slot 141 is placed above the discharge hole 15, the screw is released, allowing it to fall from the discharge hole 15 into the guide tube 151 and be discharged from the two guide tubes 151, thereby achieving material separation.

[0039] The feeding component 2 is used for feeding materials. The feeding component 2 is located on one side of the distributing component 1. The feeding component 2 includes a support frame 21. A hopper 22 is fixedly installed on the support frame 21. An arc-shaped slider 23 is slidably connected to the bottom wall of the hopper 22. An arc-shaped guide block 221 is fixedly installed on the inner wall of the hopper 22. The slider 23 is slidably connected to the guide block 221. A guide groove 231 is opened on the slider 23. A pneumatic push rod 24 is rotatably installed on the support frame 21. One end of the pneumatic push rod 24 is rotatably connected to the support frame 21, and the other end is rotatably connected to the bottom wall of the slider 23.

[0040] Furthermore, screws are stored in the hopper 22, and the pneumatic push rod 24 drives the slider 23 to rotate on the guide block 221 through the extension and retraction of the telescopic end. When the slider 23 is placed at the lowest end, multiple screws fall into the guide groove 231. When the slider 23 moves to the highest point, the screws slide out from the guide groove 231, thereby feeding the screws.

[0041] A conveying assembly 3 is installed between the material distribution assembly 1 and the feeding assembly 2. The conveying assembly 3 includes a guide rail 31. The two ends of the guide rail 31 are respectively fixedly connected to the support base 11 and the hopper 22 by brackets. A material conveying trough 311 is opened on the guide rail 31. An electromagnetic vibrator 32 is installed on the bottom wall of the guide rail 31.

[0042] Specifically, when the screw falls into the feeding groove 311 on the guide rail 31, the electromagnetic vibrator 32 drives the guide rail 31 to vibrate and feed the screw. When the limiting post 142 is at the lowest point of the sliding groove 112, the slot 141 is directly opposite the guide rail 31, and the guide rail 31 and the electromagnetic vibrator 32 can be combined to form a linear vibrating feeder, thereby improving the feeding efficiency.

[0043] The working principle and usage process of this utility model are as follows: After installation, this utility model is controlled by the corresponding controller. Screws are stored in the hopper 22. The pneumatic push rod 24 drives the slider 23 to rotate on the guide block 221 via the extension and retraction of its telescopic end. When the slider 23 is at its lowest point, multiple screws fall into the guide groove 231. When the slider 23 moves to its highest point, the screws slide out of the guide groove 231 and fall into the conveying groove 311 on the guide rail 31. The electromagnetic vibrator 32 drives the guide rail 31 to vibrate, thereby conveying the screws. When the limiting post 142 is at the lowest point of the sliding groove 112, the locking groove 141 is directly opposite the guide rail 311. 1. The electric push rod 12 drives the sliding plate 13 to move laterally in the mounting groove 111. At the same time, the limiting post 142 slides in the "V"-shaped sliding groove 112. The sliding groove 112 drives the limiting post 142 to move, so that the material distribution block 14 slides in the sliding groove 131. When the limiting post 142 is at the lowest point of the sliding groove 112, the slot 141 engages the screw. When the limiting post 142 moves to the highest point, the material distribution block 14 slides back into the sliding groove 131, thereby releasing the screw. The two material distribution blocks 14 perform material distribution. When the slot 141 is placed above the discharge hole 15, the screw is released, so that the screw falls from the discharge hole 15 into the guide tube 151.

[0044] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
